回答1:
what OS are you using? In ubuntu you need to check your version:
service mongod status, mongod --version.
If mongod is off then just restart and write the error if possible.
service mongod restart
回答2:
if you are using linux, try this command
$ sudo mongod
you are getting that because you are running
$ mongo
回答3:
First go to your mongoDB directory and in that directory go to bin directory and open terminal in that directory(bin), then run the following command:
mongod.exe
After that open another terminal in same directory and run the following command.
mongo.exe
It will resolve this issue.
回答4:
first you check it mongodb proper installed or not and also check it version compatibility
I am saying windows os setup,
set environment variable is path C:\Program Files\MongoDB\Server\3.6\bin;
then open your command prompt and type
mongod
after open another command prompt and type
mongo
